The Zen of Python Governance

!7 Change is a constant

!8 Great code requires communication

!9 People have opinions

Python Today

!11 Growth Governance Python 3.8 Farewell to Python 2 Code
and Language

!12 Growth

What's behind the growth? Web DevOps Systems Scripting

Embedded & Makers Micropython, CircuitPython, Raspberry Pi

!26 In reality, programming languages are how programmers express and
communicate ideas — and the audience for those ideas is other programmers, not computers. http://neopythonic.blogspot.com/2016/04/kings-day-speech.html Guido van Rossum Language Design

Communicating through code

!64 Web Binaries Mobile What can you do

!65 What can you do ‣ Keep up with WebAssembly
news ‣ Give a Rust / wasm / Python project a try ‣ Try Beeware and its tools. Great project for ﬁrst time contributors too. ‣ Think about the User Experience for your work

Code and Community Call to Action

–Tim O'Reilly “Contributions can encompass so much more than code.
A successful software community requires time, dedication, communication, and education as well as elegant code.”

!68 Sensible Defaults for Code and Community

!69 Respect time graceful disagreement your approach may not be
best

!70 Listen understanding consideration value ideas of others

!71 Share experiences knowledge risk and reward

!72 Trust Negativity shuts down creativity. Silencing productive discourse and
gatekeeping result in toxic workflows.

!73 Humility Long term success Learning from failures Innovation

!74 Have a bold vision

Connect the Pythonistas

– Guido van Rossum ...a programming language created by a
community fosters happiness in its users around the world. http://neopythonic.blogspot.com/2016/04/kings-day-speech.html
